Introduction Malaria is a major health problem in developing countries accounting for 2-3 million deaths per year. Malaria a tropical protozoan disease transmitted through female

Objective: The aim of this study was to investigate the effect of malarial parasites, on different biochemical liver and renal parameters. This was a retrospective and hospital-based study, which was carried out at Department of Microbiology and Central Clinical Laboratory, MGM Medical College and Hospital, Navi Mumbai, is an endemic malaria transmission.

Methods: A total of 60 samples were included in this study out of which 30 samples with peripheral blood film evidence of falciparum malaria and 30 samples of vivax malaria. Liver function tests and renal function tests were estimated by standard method.

Results: the results showed an increased level in Plasmodium falciparum than Plasmodium vivax which is statistically significant. In our study we found that Plasmodium falciparum altered more biochemical parameters than Plasmodium vivax.

Conclusions: The biochemical markers can be used as biomarkers for the confirmation of malaria.

lular protozoa of the genus Plasmodium cause malaria in humans. They include Plasmodium falciparum, P. vivax, P. ovale, and P. malariae. P. falciparum and P. vivax cause the most serious forms of the disease. [2]. Blood is a tissue that circulates in a virtually closed system of blood vessels. It is composed of solid elements-red, white blood cells, and platelets, suspended liquid medium-plasma.

Therefore, the plasma is an extracellular fluid confined within the vascular system. The water and electrolyte composition of plasma is particularly the same as that of intracellular fluid, made up of water, electrolytes, metabolites, nutrients, proteins and hormones [3].

Physicochemical properties of the blood are constant but may undergo slight variations under normal physiologic conditions. However, the relative constancy in the internal environment of the blood system exhibits wide, profound perturbation and distortions under clinically defined patho-physiologic states. Some of these conditions include malignancy, genetic defects, malnutrition, parasitic infections etc. Studies have revealed that haematologic and biochemical alterations occur in malaria infected blood and there are common complications associated with this disease. Haematologic alterations that are associated with malaria infection include anaemia, thrombocytopenia, and disseminated intravascular [4-7]. Alterations in physicochemical parameters of P. falciparum infested blood may vary with levels of malaria endemicity, presence of hae-

Discussion The present retrospective study was conducted at Microbiology Department and Central Biochemistry laboratory over a period of one year from January 2014 to December 2014, for to study the alteration in biochemical parameters during malaria by Plasmodium vivax and Plasmodium falciparum. In this study we included a total 60 confirmed malaria positive samples, out of which 30 samples were Plasmodium falciparumand and 30 samples were Plasmodium vivax. In our study we found statistically significant difference between Plasmodium vivax and falciparum species effects on liver function tests and renal function tests Table 1. Our study showed that the malarial infection affects more biochemical parameters in Plasmodium falciparum than Plasmodium vivax. Elnoman NE et al., reported higher level of AST, ALT, total bilirubin and indirect bilirubin, while the level of total protein, albumin and globulin was significantly dropped [13]. A significant positive correlation using Pearsonâ&#x20AC;&#x2122;s correlation coefficient, was found between liver enzymes, age, hemoglobin, bilirubin level (p<0.005); a negative insignificant correlation with albumin and total protein p>0.005. [13] Godse RR reported that there was significant increase in the level of SGOT, SGPT, ALP, bilirubin, creatinine and Urea [14].

Chikezie PC et al., reported serum albumin decreases in malarious subjects whereas serum creatinine concentrations of malarious subjects were increases [15]. Serum urea concentrations of malarious subjects were significantly (p < 0.05) higher than the corresponding nonmalarious age group. Subjects with moderate malaria infection showed symptoms of anaemia, alterations in nitrogen and carbohydrate metabolism and exemplified by raised serum level of urea. Adeosun OG et al., reported that the urea, creatinine and bilirubin levels were significantly elevated in the acute falciparum malarious children than in the non-parasitaemic controls [16]. Acute falciparum malaria resulted in significant reduction of total protein, albumin and glucose levels in the malarious children [16]. Malaria is a disease which causes high morbidity and mortality in patients. It can be reduced by following the biochemical parameters along with malaria diagnosis. The biochemical parameters may be used as a biomarker to differentiating vivax malaria from falciparum malaria which is severe in mortality. Our study concluded that malaria has a significant impact on biochemical profile therefore it must be considered as a leading differential diagnosis in acute febrile patients with more abnormalities including spleenomegaly and hepatomegaly.
